Superalloy without titanium, powder, method and component

Abstract

A nickel-based superalloy without titanium and a corresponding powder. A process for producing a component, wherein the alloy or the powder is used, in particular for a process for additive manufacture, especially selective laser sintering or selective laser melting. A component having an alloy or produced from the powder or produced by the process.

The invention claimed is: 
     
       1. A nickel-based superalloy, wherein the alloying elements consist of in % by weight:
 chromium (Cr): 12%-14%, 
 cobalt (Co): 9.5%-11.0%, 
 tungsten (W): 7.5%-9.5%, 
 tantalum (Ta): 1.5%-2.5%, 
 aluminum (Al): 4.5%-5.5%, 
 carbon (C): 0.04%-0.08%, 
 boron (B): 0.007%-0.01%, 
 hafnium (Hf): 0.4%-1.2%, 
 zirconium (Zr): 0.007%-0.01%; and 
 balance nickel (Ni), 
 wherein the nickel-based superalloy comprises no titanium (Ti). 
 
     
     
       2. The nickel-based superalloy of  claim 1 ,
 wherein the alloying elements consist of in % by weight: 
 chromium (Cr): 12.5%, 
 cobalt (Co): 10.5%, 
 tungsten (W): 8.5%, 
 tantalum (Ta): 2%, 
 aluminum (Al): 5%, 
 carbon (C): 0.05%, 
 boron (B): 0.009%, 
 hafnium (Hf): 0.5%, 
 zirconium (Zr): 0.009%; and 
 balance nickel (Ni), 
 wherein the nickel-based superalloy comprises no titanium (Ti). 
 
     
     
       3. A powder comprising: at least the nickel-based superalloy as claimed in  claim 1 . 
     
     
       4. A powder comprising: the nickel-based superalloy consisting of the alloying elements of  claim 1 . 
     
     
       5. A process for producing a component, comprising: producing the component with the nickel-based superalloy as claimed in  claim 1 . 
     
     
       6. The process for producing a component of  claim 5 , wherein additive manufacture, selective laser sintering, or selective laser melting is used. 
     
     
       7. A process for producing a component, comprising: producing the component with the powder as claimed in  claim 3 . 
     
     
       8. The process for producing a component of  claim 6 ,
 wherein additive manufacture, selective laser sintering, or selective laser melting is used. 
 
     
     
       9. A component comprising: the nickel-based superalloy as claimed in  claim 1 . 
     
     
       10. A component produced from the powder as claimed in  claim 3 . 
     
     
       11. A component produced by the process as claimed in  claim 5 .
